Our Most Popular Model The FCL Flexible Split-Core Current Transformer

The UL Certified FCL flexible split-core current transformer is designed for easy installation on large bus or wire conductors in order to make electrical load surveys or for continuous monitoring of current.

Directional silicon steel is used for the flexible core. Secondary windings are of copper. The entire unit is encapsulated in silicone rubber which protects against moisture, dirt, oil and corona.

Standard outputs for 1A, 5A, 0.333V, and 1V applications.
